To all 'whom 'it may camera:

Be it known that we, CARL SoHULTz and THoMAsl-VARKER, of No. 133 Fourth Avenue,

lin the city,l county, and State of New York,

have invented a new and Improved Gaseous- Liquid Injector; and we do hereby declare that the followingis a full,` clear, and exact description thereof, which will enable others skilledin Y. the art to make and use the same, reference being had to the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a sectional side elevation of this invention. Fig. 2 is a sectional planor top lview of the same.

Similar letters of reference AYindicate like parts. l

The object of this inventionis Ito heat carbonic-acid water or other gaseous liquids and filled with hot water,in such a manner that the4 gaseous liquid, while passing through'this coil, is heated to the desired temperature, and the escape or loss of a portion of the gases is avoided.

The invention consists, further,in the use of'. a lbulb of glass or other suitable material, pro# vided with an inlet and outlet tube, and applied in combination with the fountain containing the gaseous liquid, and with the pipe passing through hot water, in such a manner that the heated liquid, in passing through said bulb, will discharge a portion of its gases which accumulates in the upper part of the same, and when the pressure of those gases exceeds that of the liquid nothing but gas will discharge `from the bulb; but as soon as the pressure of fthe gas is reduced the liquid will rise in the bulb, and only liquid divested of a portion of its gases will discharge, and thus an alternate jet of liquid and of gas is obtained. d l.

Arepresents an apparatus in which carbonicacid water or other gaseous liquid can be made, and which is composed of the generator B and receiver C; but, instead of this apparatus, any vessel which is charged with the gaseous of a screw-thread, so that it can be readily re.

moved and replaced by another of different shape. Y

Interposed between the pipe which forms the coil c is the bulb g, of glass or any other-suit..

able material. This bulb is provided with two openin gs-one to admit the liquid and vthe other Atodicharge the suino-and when t'hcapparatus A is in use it is covered by warm or hot water. It is so connected to the coil that it can be taken out or put in in a. short time. When the lbulb is not used the gaseous liquidfrom the fountain C passes through the coil, which is covered by hotwater, and in itstpassage through. said coil the-liquid is hea-ted; but the tube which forms the coil, being completely filled-- with liquid, does not allow the. gases to sepa.- rate themselves from the liquid, and an injeclf., tion can thus be taken of hot carbonio-acid water or other gaseous liquid. ASuchen-injector vhas been heretore considered an impos' sibility, because, in heating the carbonio-,acid water lor other gaseous liquid in,v anyother manner but that above stated, the gases escape from the liquid, and the patient derives no beuclit from the same. y gf -In many cases it may be'desirable to obtainl an alternate jet of liquid and of carbonio-acid or other gas, and in such cases the bulb g is used. As the gaseous liquid passes through' this bulb, which is covered-with hot' water, as-

previously stated, the carbonio-acid or other` gas or gases free themselves from the liquid and occupy the upper portion of said bulb.

The pressure ofthe gases thusinclose'd rises, until the liquid is forced back from the discharge-opening and a portionI of the gases from'n the upper part 'of the bulbdscharges, soon fas the pressure of said gases isreduced by this escape the liquid risesin thebulb and a jet of'v liquid discharges from the spout, and bythesc gaseous liquid can be obtained without allowing theescape of ga's;v

2. The application' of a bulb, g, in combination with the coil c, vessel d, fountaiii A, and tip'f, constructed and operating substantially as and for the purpose described. V
